6.3 Licensing
This section describes FibeAir IP-10E’s licensing structure. FibeAir IP-10E offers a pay-as-you-grow concept to reduce network costs. Future capacity growth and additional functionality is enabled with license keys and an innovative stackable nodal solution using the same hardware. Licenses are divided into two categories:
Per Radio – Each IDU (both sides of the link) require a license.
Per Configuration – Only one license is required for the system.
A 1+1 configuration requires the same set of licenses for both the active and the protected IDU.
In nodal configuration for licenses that are not per radio, licenses should be assigned to the main (bottom) IDU in the enclosure.
6.3.1 Working with License Keys
Ceragon provides a web-based License Management System (LMS). The LMS enables authorized users to generate license keys, which are generated per IDU serial number. In order to upgrade a license, the license-key must be entered into the IP-10E, followed by a cold reset. When the system returns online following the reset, its license key is checked, enabling access to new capacities and/or features. For more detailed information, refer to FibeAir IP-10 License Management System, DOC-00019183.
6.3.2 Licensed Features
As your network expands and additional functionality is desired, license keys can be purchased for the following features:
Adaptive Coding and Modulation (ACM)

7.2.2 Additional Interfaces
Terminal Console – A local craft terminal can be connected to the terminal console for local CLI management of the individual IDU. If the IDU is the main unit, access to other units in the configuration is also available through the Terminal Console.
External Alarms – IP-10E supports five external alarms, located towards the left of the front panel. There are five inputs, with configurable triggers, alarm texts, and alarm severity, and one output.
Backplane Connector – IP-10E has an extra connector on the back panel for connection to the backplane used in nodal configurations. Refer to Nodal Configuration on page 35.
7.2.3 Power Options
IP-10E has a DC input voltage nominal rating of -48V.
Some hardware versions include a dual-feed power connection for increased protection. In dual power units, the system will indicate whether received voltage in each connection is above or below the threshold power of approximately 40.5V, as follows:
The LED (and its WEB representation) will only be on if the voltage is above the threshold.
An alarm is raised if voltage is below the threshold.

7.3 Nodal Configuration
IP-10E can be used in two distinct modes of operation:
Standalone configuration – Each IP-10E IDU is managed individually.
Nodal configuration – Up to six IP-10E IDUs are stacked in a dedicated modular shelf, and act as a single network element with multiple radio links.
The following features are centralized in a nodal configuration:
Management
Ethernet Switching
A nodal setup supports any combination of 1+0, 1+1, and 2+0/XPIC configurations.
7.3.1 Nodal Configuration Benefits
The stackable nodal configuration offers many advantages. For new systems, the nodal configuration offers:
Low initial investment without compromising future growth potential
Risk-free deployment in light of unknown future growth patterns:
Additional capacity
Additional sites
Additional redundancy
For migration and replacement scenarios, the nodal configuration offers:
Optimized tail-site solution
Low initial footprint that can be increased gradually as legacy equipment is swapped
7.3.2 IP-10E Nodal Design
Each IP-10E IDU in a nodal configuration operates as either the main unit or an extension unit. The IDU’s role is determined by its position in the nodal enclosure, with the lowest unit in the enclosure (Unit Number 1) always serving as the main unit.
The main unit performs the following functions:
Provides a central controller for management
Provides radio and line interfaces
Extension units provide radio and line interfaces, and are accessed through the main unit.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 36 of 167
7.3.3 Nodal Enclosure Design
Two types of shelves are available for a nodal configuration:
Main Nodal Enclosure – Each node must have a main nodal enclosure, which can hold two IP-10E IDUs.
Extension Nodal Enclosure –Up to two extension nodal enclosures can be stacked on top of the main nodal enclosure. Each extension nodal enclosure can contain two IP-10E IDUs.
Main Nodal Enclosure
Extension Nodal Enclosure
Each nodal enclosure includes a backplane. The rear panel of an IP-10E IDU includes an extra connector for connection to the backplane. The following interfaces are implemented through the backplane:
Multi-Radio
Protection
XPIC
IP-10E IDUs are hot-swappable, and additional extension nodal enclosures and IDUs can be added in the field as required, without affecting traffic.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 37 of 167
Scalable Nodal Enclosure
Using the stacking method, units in the bottom nodal enclosure act as main units, whereby a mandatory active main unit can be located in either of the two slots, and an optional standby main unit can be installed in the other slot. The switchover time is <50 msecs for all traffic-affecting functions. Units located in nodal enclosures other than the one on the bottom act as expansion units.
Radios in each pair of units can be configured as either dual independent 1+0 links, or single fully-redundant 1+1 HSB links.
7.3.4 Nodal Management
In a nodal configuration, all management is performed through the main unit. The main unit communicates with the extension units through the nodal backplane.
The main unit’s CPU operates as the node’s central controller, and all management frames received from or sent to external management applications must pass through the CPU.
A nodal configuration has a single IP management address, which is the address of the main unit. In a protected 1+1 configuration, the node has two IP addresses, those of each of the main units. The IP address of the active main unit is used to manage the node.
Several methods can be used for IP-10E node management:
Local terminal CLI
CLI via telnet
Web-based management
SNMP
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 38 of 167
The PolyView NMS represents the node as a single unit.
The Web-Based EMS enables access to all IDUs in the node from its main window.
In addition, the management system provides access to other network equipment through in-band or out-of-band network management.
To ease the reading and analysis of several IDU alarms and logs, the system time should be synchronized to the main unit’s time.
7.3.5 Centralized System Features
The following IP-10E functions are configured centrally through the main unit in a nodal configuration:
IP Communications – All communication channels are opened through the main unit’s IP address.
User Management – Login, adding users, and deleting users are performed centrally.
Nodal Time Synchronization – System time is automatically synchronized for all IDUs in the node.
Nodal Software Version Management – Software can be upgraded or downgraded in all IDUs in the node from the main unit.
Nodal Configuration Backup – Configuration files can be created, downloaded, and uploaded from the main unit.
Nodal Reset – Extension units can be reset individually or collectively both from the main unit and locally.
All other functions are performed for each IDU individually.
7.3.6 Ethernet Connectivity in Nodal Configurations
Ethernet traffic in a nodal configuration is supported by interconnecting IDU switches with external cables. Traffic flow (dropping to local ports, sending to radio) is performed by the switches, in accordance with learning tables.
Each IDU in the stack can be configured individually for Smart Pipe or Carrier Ethernet Switching modes. For more information about Ethernet switching, refer to Ethernet Switching on page 60.

7.4.1 1+1 HSB Protection
A 1+1 configuration scheme can be used to provide full protection in the event of IDU or RFU failure. The two IDUs operate in active and standby mode. If there is a failure in the active IDU or RFU, the standby IDU and RFU pair switches to active mode.
In a 1+1 configuration, the protection options are as follows:
Standalone – The IDUs must be connected by a dedicated Ethernet protection cable. Each IDU has a unique IP address.
Nodal – The IDUs are connected by the backplane of the nodal enclosure. There is one IP address for each of the main units.

3 x 1+1 Aggregation Site
7.4.2 2+0 Multi-Radio and 2+0 Multi-Radio with IDU and Line Protection
2+0 Multi-Radio provides a significant degree of protection, in addition to doubling capacity by enabling two separate radio carriers to be shared by a single Ethernet port. In the event of RFU failure, or failure of the slave IDU, one RFU and IDU remain in operation, with graceful degradation of service to ensure that not all data is lost, but rather, a reduction of bandwidth occurs. However, if there is a failure of the master IDU, traffic and management access is lost.
The IDU and line protection option eliminates this potential point of failure by providing for the standby IDU to assume the role of master IDU in the event of failure in the master IDU. Thus, Ethernet traffic is maintained with reduced bandwidth in the event of any single unit failure. Graceful degradation is provided with the help of IP-10E’s integrated QoS mechanism, which ensures that high-priority traffic is maintained in the event of reduced bandwidth. For further details about Multi-Radio, refer Multi-Radio on page 48.
Note: A nodal enclosure is required for 2+0 Multi-Radio, both with and without IDU and line protection.
7.4.3 2+2 HSB Protection
2+2 HSB protection provides full redundancy between two pairs of IDUs. Each pair is a 2+0 link, which can be configured for XPIC or in different frequencies. If there is a failure in one of these pairs, the other pair takes over.
A 2+2 protection scheme must be implemented by means of a nodal configuration. A 2+2 configuration consists of two pairs of IP-10E IDUs, each inserted in its own main nodal enclosure, with a protection cable to connect the main IDUs in each node. Protection is performed between the pairs. At any given time, one pair is active and the other is standby.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 42 of 167
A 2+2 scheme is only possible between units in the main nodal enclosure. Extension nodal enclosures cannot be used in a 2+2 configuration.
2+2 protection can be used together with XPIC and/or Multi-Radio. The following figure illustrates a 2+2 configuration with both XPIC and Multi-Radio. The RFUs marked V are set to vertical polarization, while the RFUs marked H are set to horizontal polarization.

8.1 Adaptive Coding and Modulation (ACM)
FibeAir IP-10E employs full-range dynamic ACM. IP-10E’s ACM mechanism copes with 90 dB per second fading in order to ensure high transmission quality. IP-10E’s ACM mechanism is designed to work with IP-10E’s QoS mechanism to ensure that high priority voice and data packets are never dropped, thus maintaining even the most stringent service level agreements (SLAs).
The hitless and errorless functionality of IP-10E’s ACM has another major advantage in that it ensures that TCP/IP sessions do not time-out. Without ACM, even interruptions as short as 50 milliseconds can lead to timeout of TCP/IP sessions, which are followed by a drastic throughout decrease while these sessions recover.
Note: ACM cannot be used together with BBS Frequency and Space Diversity. It can be and often is used with Multi-Radio, but cannot be used with 2+0 Multi-Radio with IDU and line protection.
8.1.1 Eight Working Points
IP-10E implements ACM with eight available working points, as follows:
ACM Working Points (Profiles)
Working Point (Profile) Modulation
Profile 0 QPSK
Profile 1 8 PSK
Profile 2 16 QAM
Profile 3 32 QAM
Profile 4 64 QAM
Profile 5 128 QAM
Profile 6 256 QAM – Strong FEC
Profile 7 256 QAM – Light FEC
Adaptive Coding and Modulation with Eight Working Points
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 45 of 167
8.1.2 Hitless and Errorless Step-by-Step Adjustments
ACM works as follows. Assuming a system configured for 128 QAM with ~170 Mbps capacity over a 28 MHz channel, when the receive signal Bit Error Ratio (BER) level reaches a predetermined threshold, the system preemptively switches to 64 QAM and the throughput is stepped down to ~140 Mbps. This is an errorless, virtually instantaneous switch. The system continues to operate at 64 QAM until the fading condition either intensifies or disappears. If the fade intensifies, another switch takes the system down to 32 QAM. If, on the other hand, the weather condition improves, the modulation is switched back to the next higher step (e.g., 128 QAM) and so on, step by step .The switching continues automatically and as quickly as needed, and can reach all the way down to QPSK during extreme conditions.
Adaptive Coding and Modulation
8.1.3 Configurable Minimum ACM Profile
When using ACM, the user can configure a minimum ACM profile. When a minimum ACM profile is configured, the system will not step down to any modulation below the minimum. For example, if the configured minimum ACM profile is 3 (32 QAM), stepping down below 32 QAM is not allowed. If the channel’s SNR degrades below the 32 QAM threshold, the radio will lose carrier synchronization, and will report loss of frame.
8.1.4 ACM Benefits
The advantages of IP-10E’s dynamic ACM include:
Maximized spectrum usage
Increased capacity over a given bandwidth
Eight modulation/coding work points (~3 db system gain for each point change)

An integrated QoS mechanism enables intelligent congestion management to ensure that high priority traffic is not affected during link fading
8.1.5 ACM and Built-In Quality of Service
IP-10E’s ACM mechanism is designed to work with IP-10E’s QoS mechanism to ensure that high priority voice and data packets are never dropped, thus maintaining even the most stringent SLAs. Since QoS provides priority support for different classes of service, according to a wide range of criteria, you can configure IP-10E to discard only low priority packets as conditions deteriorate. For more information on IP-10E’s QoS and Enhanced QoS functionality, refer to Integrated QoS Support on page 61.
If you want to rely on an external switch’s QoS, ACM can work with them via the flow control mechanism supported in the radio.
8.1.6 ACM with Adaptive Transmit Power
When planning ACM-based radio links, the radio planner attempts to apply the lowest transmit power that will perform satisfactorily at the highest level of modulation. During fade conditions requiring a modulation drop, most radio systems cannot increase transmit power to compensate for the signal degradation, resulting in a deeper reduction in capacity. IP-10E is capable of adjusting power on the fly, and optimizing the available capacity at every modulation point, as illustrated in the figure below. This figure shows how operators that want to use ACM to benefit from high levels of modulation (e.g., 256 QAM) must settle for low system gain, in this case, 18 dB, for all the other modulations as well. With FibeAir IP-10E, operators can automatically adjust power levels, achieving the extra 4 dB system gain that is required to maintain optimal throughput levels under all conditions.

8.2 Multi-Radio
Multi-Radio enables two separate radio carriers to be shared by a single Ethernet port. This provides an Ethernet link over the radio with double capacity, while still behaving as a single Ethernet interface. The IDUs in a Multi-Radio setup operate in master and slave mode.
In Multi-Radio mode, traffic is divided among the two carriers optimally at the radio frame level without requiring Ethernet Link Aggregation, and is not dependent on the number of MAC addresses, the number of traffic flows, or momentary traffic capacity. During fading events which cause ACM modulation changes, each carrier fluctuates independently with hitless switchovers between modulations, increasing capacity over a given bandwidth and maximizing spectrum utilization.
The result is 100% utilization of radio resources in which traffic load is balanced based on instantaneous radio capacity per carrier and is independent of data/application characteristics, such as the number of flows or capacity per flow.

Note: 2+0 Multi-Radio requires a nodal configuration.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 49 of 167
8.2.1 IDU and Line Protection in Multi-Radio
Basic 2+0 Multi-Radio provides for protection and graceful degradation of service in the event of failure of an RFU or the slave IDU. This ensures that if one link is lost, not all data is lost. Instead, bandwidth is simply reduced until the link returns to service.
There is also an option for additional IDU and line protection with 2+0 Multi Radio. With the IDU and line protection option, the master IDU is also protected in the event of failure. If there is a failure in the master IDU, the slave IDU becomes the master, and continues to provide service. Thus, a 2+0 Multi-Radio configuration with IDU and line protection provides protection for the failure of any IDU or RFU in the node. Graceful degradation is provided with the help of IP-10E’s integrated QoS mechanism, which ensures that high-priority traffic is maintained in the event of reduced bandwidth.
The IDU and line protection feature protects Ethernet traffic. It also protects management of the node, since node management is handled by the master IDU.
Note: 2+0 Multi-Radio, both with and without IDU and line protection, requires a nodal configuration.
Multi-Radio can also be used in a 2+2 configuration. As in any 2+2 configuration, this provides full protection.
FibeAir® IP-10 E-Series Product Description

8.3 XPIC Support
Cross Polarization Interference Canceller (XPIC) is one of the best ways to break the barriers of spectral efficiency. Using dual-polarization radio over a single-frequency channel, a dual polarization radio transmits two separate carrier waves over the same frequency, but using alternating polarities. Despite the obvious advantages of dual-polarization, one must also keep in mind that typical antennas cannot completely isolate the two polarizations. In addition, propagation effects such as rain can cause polarization rotation, making cross-polarization interference unavoidable.
Dual Polarization
The relative level of interference is referred to as cross-polarization discrimination (XPD). While lower spectral efficiency systems (with low SNR requirements such as QPSK) can easily tolerate such interference, higher modulation schemes cannot and require XPIC. IP-10E’s XPIC algorithm enables detection of both streams even under the worst levels of XPD such as 10 dB. IP-10E accomplishes this by adaptively subtracting from each carrier the interfering cross carrier, at the right phase and level. For high-modulation schemes such as 256 QAM, an improvement factor of more than 20 dB is required so that cross-interference does not adversely affect performance.
8.3.1 XPIC Benefits
The advantages of FibeAir IP-10E’s XPIC option include:
BER of 10e-6 at a co-channel sensitivity of 5 dB
Multi-Radio Support
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 51 of 167
8.3.2 XPIC Implementation
In a single channel application, when an interfering channel is transmitted on the same bandwidth as the desired channel, the interference that results may lead to BER in the desired channel.
IP-10E supports a co-channel sensitivity of 33 dB at a BER of 10e-6. When applying XPIC, IP-10E transmits data using two polarizations: horizontal and vertical. These polarizations, in theory, are orthogonal to each other, as shown in the figure below
XPIC - Orthogonal Polarizations
In a link installation, there is a separation of 30 dB of the antenna between the polarizations, and due to misalignments and/or channel degradation, the polarizations are no longer orthogonal. This is shown in the figure below.
XPIC – Impact of Misalignments and Channel Degradation
Note that on the right side of the figure you can see that CarrierR receives the H+v signal, which is the combination of the desired signal H (horizontal) and the interfering signal V (in lower case, to denote that it is the interfering signal). The same happens in CarrierL = “V+h. The XPIC mechanism takes the data from CarrierR and CarrierL and, using a cost function, produces the desired data.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 52 of 167
XPIC – Impact of Misalignments and Channel Degradation
IP-10E’s XPIC reaches a BER of 10e-6 at a co-channel sensitivity of 5 dB! The improvement factor in an XPIC system is defined as the SNR@threshold of 10e-6, with or without the XPIC mechanism.
8.3.3 XPIC and Multi-Radio
XPIC radio may be used to deliver two separate data streams, such as 2xSTM1 or 2xFE. But it can also deliver a single stream of information such as Gigabit Ethernet, or STM-4. The latter requires a de-multiplexer to split the stream into two transmitters, as well as a multiplexer to join it again in the right timing because the different channels may experience a different delay. This feature is called Multi-Radio.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 53 of 167
8.4 Space and Frequency Diversity
In long distance wireless links, multipath phenomena are common. Both direct and reflected signals are received, which can cause distortion of the signal resulting in signal fade. The impact of this distortion can vary over time, space, and frequency. This fading phenomenon depends mainly on the link geometry and is more severe at long distance links and over flat surfaces or water. It is also affected by air turbulence and water vapor, and can vary quickly during temperature changes due to rapid changes in the reflections phase.
Fading can be flat or dispersive. In flat fading, all frequency components of the signal experience the same magnitude of fading. In dispersive, or frequency-selective fading, different frequency components of the signal experience decorrelated fading.
Direct and Reflected Signals
Space Diversity and Frequency Diversity are common ways to negate the effects of fading caused by multipath phenomena.
Space Diversity is implemented by placing two separate antennas at a distance from one another that makes it statistically likely that if one antenna suffers from fading caused by signal reflection, the other antenna will continue to receive a viable signal.
Frequency Diversity is implemented by configuring two RFUs to separate frequencies. The IDU selects and transmits the better signal.
IP-10E offers Frequency Diversity and two methods of Space Diversity:
Baseband Switching (BBS) Frequency and Space Diversity – Each IDU receives a separate signal from a separate antenna. Each IDU compares each of the received signals, and enables the bitstream coming from the receiver with the best signal. Switchover is errorless (“hitless switching”).
IF Combining (IFC) Space Diversity – Signals from two separate antennas are combined in phase with each other to maximize the signal to noise ratio. IF Combining is performed in the RFU.
Note: BBS Frequency and Space Diversity cannot be used together with ACM.

Diversity Signal Flow
Note: Frequency and space diversity configurations offer the option of Ethernet line protection using Multi-Unit LAG. For more information, refer to Ethernet Line Protection on page 72.
8.4.1 Baseband Switching (BBS) Frequency Diversity
BBS frequency diversity requires two antennas and RFUs. Each RFU in a frequency diversity node is configured to a different frequency. Any RFU type supported by IP-10E can be used in a BBS Frequency Diversity configuration.
Both the active and the standby RFUs transmit simultaneously. One RFU sends its signal to the active IDU, while the other RFU sends its signal to the standby IDU. The IDUs share these signals through the nodal backplane, such that each IDU receives data from both RFUs. The diversity mechanism, which is located within the IDU Mux, is active in both IDUs, and selects the better signal based on:
Faulty signal indication – An indication from the Modem to the Mux, signaling that there are more errors in the traffic stream than it can correct. The purpose of this indication is to alert the Mux to the fact that those errors are on their way, requiring a hitless switchover in order to prevent them from entering the data stream from the Mux onward.
OOF (Out-of-Frame) – When the Mux identifies an OOF event, it will initiate a switchover.
BBS Frequency Diversity requires a 1+1 configuration in which there are two IDUs and two RFUs protecting each other at both ends of the link. In the event of IDU failure, Frequency Diversity is lost until recovery, but the system remains protected through the ordinary switchover mechanism.
8.4.2 Baseband Switching (BBS) Space Diversity
BBS Space Diversity requires two antennas and RFUs. The antennas must be separated by approximately 15 to 20 meters. Any RFU type supported by IP-10E can be used in a BBS Space Diversity configuration.
One RFU sends its signal to the active IDU, while the other RFU sends its signal to the standby IDU. The IDUs share these signals through the nodal backplane,
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 55 of 167
such that each IDU receives data from both RFUs. The diversity mechanism, which is located within the IDU Mux, is active in both IDUs, and selects the better signal based on:
Faulty signal indication – An indication from the Modem to the Mux, signaling that there are more errors in the traffic stream than it can correct. The purpose of this indication is to alert the Mux to the fact that those errors are on their way, requiring a hitless switchover in order to prevent them from entering the data stream from the Mux onward.
OOF (Out-of-Frame) – When the Mux identifies an OOF event, it will initiate a switchover.
BBS Space Diversity requires a 1+1 configuration in which there are two IDUs and two RFUs protecting each other at both ends of the link. In the event of IDU failure, Space Diversity is lost until recovery, but the system remains protected through the ordinary switchover mechanism.
8.4.3 IF Combining (IFC)
IFC requires a dual-receiver RFU such as the FibeAir 1500HP. The RFU receives and processes both signals, and combines them into a single, optimized signal. The IFC mechanism gains up to 2.5 dB in system gain.
8.4.4 Diversity Type Comparison

8.7 Ethernet Switching
IP-10E supports three modes for Ethernet switching:
Smart Pipe – Ethernet switching functionality is disabled and only a single Ethernet interface is enabled for user traffic. The unit effectively operates as a point-to-point Ethernet microwave radio.
Managed Switch – Ethernet switching functionality is enabled based on VLANs.
Metro Switch – Ethernet switching functionality is enabled based on an S-VLAN-aware bridge.
Ethernet Switching
Each switching mode supports QoS. For more information, refer to Integrated QoS Support on page 61.
Smart Pipe is the default mode. Managed Switch and Metro Switch require a license. For more information, refer to Licensing on page 23.
8.7.1 Smart Pipe Mode
Using Smart Pipe mode, only a single Ethernet interface is enabled for user traffic and IP-10E acts as a point-to-point Ethernet microwave radio. In Smart Pipe mode, any of the following ports can be used for Ethernet traffic:
Eth1: GbE interface (Optical GbE-SFP or Electrical GbE – 10/100/1000)
Eth3: Fast Ethernet interface
All traffic entering the IDU is sent directly to the radio, and all traffic from the radio is sent directly to the Ethernet interface.
In Smart Pipe mode, the other Fast Ethernet interfaces can either be configured as management interfaces or they are shut down. In protection mode, only the Optical GbE-SFP port acts as a trigger for switchover.

8.8 Integrated QoS Support
IP-10E offers integrated QoS functionality in all switching modes. In addition to its standard QoS functionality, IP-10E offers an enhanced QoS feature. Enhanced QoS is license-activated.
IP-10E’s standard QoS provides for four queues and six classification criteria. Ingress traffic is limited per port, Class of Service (CoS), and traffic type. Scheduling is performed according to either Strict Priority (SP), Weighted Round Robin (WRR), or Hybrid WRR/SP scheduling.
IP-10E’s enhanced QoS adds four additional queues for a total of eight. Enhanced QoS also adds an additional two classification criteria. Enhanced QoS provides hierarchical scheduling, with four scheduling priorities and Weighted Fair Queuing (WFK) between queues in the same priority. Enhanced QoS also offers Weighted Random Early Discard (WRED) for congestion management, in addition to tail-drop, as provided by standard QoS.
For a full comparison between IP-10E’s standard and enhanced QoS features, refer to Standard and Enhanced QoS Comparison on page 67.
8.8.1 QoS Overview
QoS is a method of classification and scheduling employed to ensure that Ethernet packets are forwarded and discarded according to their priority. QoS works by slowing unimportant packets down, or, in cases of extreme network traffic, discarding them entirely. This enables more important packets to reach their destination as quickly as possible. Once the router knows how much data it can queue on the modem at any given time, it can shape traffic by delaying unimportant packets and filling the pipe with important packets first, then using any leftover space to fill the pipe in descending order of importance.
Since QoS cannot speed up packets, it takes the total available upstream bandwidth, calculates the amount of high priority data, places the high priority data in the buffer, and repeats the process with each lower priority class in turn until the buffer is full or there is no further data. Any excess data is held back or "re-queued" at the front of the line, where it will be evaluated in the next pass.
Priority is determined by packet. The number of levels depends on the router. As the names imply, Low/Bulk priority packets are given the lowest priority, while High/Premium packets are given the highest priority.
QoS packets may be prioritized by a number of criteria, including criteria generated by applications themselves. The most common QoS classification techniques are MAC Address, Ethernet Port, and TCP/IP Port.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 63 of 167
8.8.2 IP-10E Standard QoS
Using IP-10E’s standard QoS functionality, the system examines the incoming traffic and assigns the desired priority according to the marking of the packets (based on the user port/L2/L3 marking in the packet). In case of congestion in the ingress port, low priority packets are discarded first.
The user has the following classification options:
Source Port
VLAN 802.1p
VLAN ID
MAC SA/DA
IPv4 TOS/DSCP
IPv6 Traffic Class
After classification, traffic policing/rate-limiting can optionally be applied per port/CoS.
IP-10E system has four priority queues that are served according to three types of scheduling, as follows:
Strict Priority – All top priority frames egress towards the radio until the top priority queue is empty. Then, the next lowest priority queue’s frames egress, and so on. This approach ensures that high priority frames are always transmitted as soon as possible.
Weighted Round Robin (WRR) – Each queue can be assigned a user-configurable weight from 1 to 32.
Hybrid – One or two highest priority queues use Strict Priority and the others use WRR.
Shaping is supported per interface on egress.

8.8.5 Enhanced QoS
Enhanced QoS provides additional QoS functionality on the egress path towards the radio interface. Enhanced QoS requires an upgrade license. Refer to Licensing on page 23.
The following are the main features of enhanced QoS:
Eight queues instead of four
Enhanced classification:
Classifier assigns each frame a queue and a CIR/EIR designation
Criteria – Same as standard QoS with addition of:
- MPLS EXP bits
- UDP port
Re-marking of 802.1p bit in the frame VLAN header (optional)

Shaping per port and per queue
Enhanced QoS enables differentiated services with strict SLA while maximizing network resource utilization.
IP-10E Enhanced QoS
8.8.6 Weighted Random Early Detection
One of the key features of IP-10E’s enhanced QoS is the use of Weighted Random Early Detection (WRED) to manage congestion scenarios. WRED provides several advantages over the standard tail-drop congestion management method.
WRED enables differentiation between higher and lower priority traffic based on CoS.
Moreover, WRED can increase capacity utilization by eliminating the phenomenon of global synchronization, which can occur when TCP flows sharing bottleneck conditions receive loss indications at around the same time. This can result in periods during which link bandwidth utilization can drop to as low as 75%.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 66 of 167
Synchronized Packet Loss
In contrast, WRED begins dropping packets randomly when the queue begins to fill up, with increased probability. This increases capacity utilization to almost 100%.

8.8.8 Enhanced QoS Benefits
The main benefits of enhanced QoS are:
The addition of UDP ports and MPLS EXP bits as classification criteria provides for more granular CoS classification (i.e., for 1588v2 control frames and MPLS PWE3 services).
The use of eight CoS queues with enhanced scheduling schemes support enables highly granular traffic management for differentiated services.
Statistics per CoS queue, including transmitted and dropped frames, enables monitoring network utilization and the detection of “pinch points.”
Shaping per queue as well as per port limits and controls packet bursts, resulting in improved utilization and end-to-end latency.
Weighted Random Early Discard (WRED) improves utilization and behavior of TCP flows.
CIR/EIR-based congestion management support (color-awareness) enables support of EIR traffic without affecting CIR traffic.

8.9 Spanning Tree Protocol (STP) Support
IP-10E supports the following spanning tree Ethernet resiliency protocols:
Rapid Spanning Tree Protocol (RSTP) (802.1w)
Carrier Ethernet Wireless Ring-optimized RSTP
8.9.1 RSTP
RSTP ensures a loop-free topology for any bridged LAN. Spanning tree enables a network design to include spare (redundant) links for automatic backup paths, with no danger of bridge loops, and without the need for manual enabling and disabling of the backup links. Bridge loops must be avoided since they result in network flooding.
In a general topology, there can be more than one loop, and therefore more than one bridge with ports in a blocking state. For this reason, RSTP defines a negotiation protocol between each two bridges, and processing of the BPDU (Bridge Protocol Data Units), before each bridge propagates the information. This serial processing increases the convergence time.
8.9.2 Carrier Ethernet Wireless Ring-Optimized RSTP
IP-10E’s proprietary RSTP implementation is optimized for Carrier Ethernet wireless rings. Ring-optimized RSTP enhances the RSTP algorithm for ring topologies, accelerating the failure propagation relative to ordinary RSTP.
In a ring topology, after the convergence of RSTP, only one port is in a blocking state. RSTP is enhanced for ring topologies by broadcasting the BPDU in order to transmit the notification of the failure to all bridges in the ring.
With IP-10E’s ring-optimized RSTP, failure propagation is much faster than with regular RSTP. Instead of link-by-link serial propagation, the failure is propagated in parallel to all bridges. In this way, the bridges that have ports in alternate states immediately place them in the forwarding state.
The figure below shows an example of a ring topology using ring-optimized RSTP. In this figure, Switch A is the Root bridge. After the protocol converges, a port in Switch C becomes the Alternate Port, and blocks all transmitted and received traffic.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 69 of 167
Ring-Optimized RSTP Solution
8.9.3 Ring-Optimized RSTP Limitations
IP-10E’s proprietary ring-optimized RSTP is not interoperable with other ring RSTP implementations from third-party vendors.
Ring RSTP is designed to provide improved performance in ring topologies. For other topologies, the RSTP algorithm will converge but performance may take several seconds. For this reason, there should be only two edge ports in every node, and only one loop.
Ring RSTP can be used in Managed Switch and Metro Switch applications, but not in Smart Pipe applications.
Ring RSTP can be used in a 1+1 protection configuration, but in some cases, the convergence time may be above one second.

8.10 Ethernet Line Protection
IP-10E offers a number of Ethernet line protection options for various multi-unit configuration scenarios in which two IP-10E IDUs are connected to an external switch or router. These are:
Single Interface with Splitter – A single interface in the external switch or router is connected to each of the two IDUs using a splitter. A splitter can be used with Fast Ethernet ports and optical GbE ports.
Dual Interface with Optical Splitter – Two interfaces in the external switch or router are configured as a static LAG, and each interface is connected to each IDU using a splitter. Splitters can be used with Fast Ethernet ports and optical GbE ports.
Dual Interface with Multi-Unit LAG – Two interfaces in the external switch or router are configured as a static LAG, and each interface is connected to one IDU. Full protection of each interface is provided by a LAG that includes interfaces in both IDUs. Multi-Unit LAG can be used with both optical and electrical GbE ports.
Hardware Protection with Single Interface Using Optical
Splitter
Full protection with Dual Interface Using Optical Splitters and LAG
Full Protection Using Multi-Unit LAG
All of these line protection methods are available for any of the following configurations:
1+1 HSB
2+0 Multi Radio with IDU and Line Protection
2+2 Multi-Radio
All BBS diversity configurations
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 73 of 167
8.10.1 Multi-Unit LAG
With Multi-Unit LAG, the switch or router relates to the IDUs as a single device. There is no need for splitters, and Multi-Unit LAG can be used to protect either the electrical GbE ports or the optical GbE ports. In contrast, splitters can only be used to protect optical GbE ports or Fast Ethernet ports. Multi-Unit LAG can only be used in Smart Pipe mode. The service disruption time in case of failure in one of the LAG physical ports is less than 50ms in most cases using Multi-Unit LAG.
An IP-10E system using Multi-Unit LAG has dual (redundant) GbE interfaces. Each of these interfaces is connected to a separate interface on an external switch or router. The IP-10E interfaces are active and enabled on both the active or master unit and the standby or slave unit. On the external unit, a static LAG must be configured on the interfaces that are connected to the IDUs.
If the IP-10E IDUs are in Multi-Radio mode with IDU and line protection, any link failure triggers graceful degradation and is transparent to the external unit. If an IDU itself experiences unit failure, the interface to which it is connected on the external unit is disabled. If the disabled IDU is the standby unit, or if it is the active unit and Multi-Radio with IDU and line protection is enabled, the functioning IDU maintains connectivity with the external unit via the interface to which the functioning IDU is connected.

8.11 Asymmetrical Scripts
IP-10E provides several asymmetrical radio script options that enable users to optimize spectrum use by increasing downlink capacity and decreasing uplink capacity by at least 50%.
Traditionally, microwave point-to-point links are symmetrical, providing equal amounts of bandwidth for TX and RX traffic flows. However, in many cellular applications, the demand for bandwidth is asymmetrical, with a much greater demand for downlink than for uplink bandwidth.
For the purpose of illustration, assume a chain that consists of two 14 MHz, for a total of 28 MHz. The following figure depicts a symmetrical configuration that uses two adjacent spectrum segments of 7 MHz each. Each signal in the link consumes two segments of 7 MHz each, for a total of 14 MHz on the uplinks and 14 MHz on the downlinks.
Symmetrical Chain Example
The following is an example of an asymmetrical chain using the same 14MHz channels in slices of 7 MHz. The entire 28 MHz uplink and downlink spectrum is divided into eight segments of 7 MHz each, but one segment is moved from the right uplink to the left downlink, increasing its capacity by 50%, from 14 MHz to 21 MHz. Similarly, one segment is moved from the left uplink to the right downlink, expanding the capacity of the right downlink by 50% (from 14 MHz to 21 MHz.
Note: This example shows just one of several ways in which capacity can be reallocated in an asymmetrical configuration.
Asymmetrical Chain Example
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 75 of 167
The following illustration provides an example of a symmetrical aggregation site in which the right link aggregates traffic from two downlinks. In this example, all the links are symmetrical, while the aggregation link has double the capacity of each of the downlinks. For purposes of this example, the downlinks each have a capacity of 14 MHz, consisting of two 7 MHz segments. The aggregation link has a capacity of 28 MHz, consisting of four 7 MHz segments.
Symmetrical Aggregation Site Example
The aggregation site shown in this example can be rearranged asymmetrically to provide 42 MHz to the aggregation downlink by combining six segments with 7 MHz in each segment. The capacity of the other downlinks can be increased to 21 MHz by combining three segments with 7 MHz in each segment for each downlink.
Note: This example shows just one of several ways in which capacity can be reallocated in an asymmetrical configuration.
Asymmetrical Aggregation Site Example
Notes: There are asymmetrical scripts with and without ACM and with and without XPIC.
A license is required in order to use asymmetrical scripts. Refer to Licensing on page 23.

8.12 Synchronization Support
Synchronization is an essential part of any mobile backhaul solution and is sometimes required by other applications as well.
Two unique synchronization issues must be addressed for mobile networks:
Frequency Lock: Applicable to GSM and UMTS-FDD networks.
Limits channel interference between carrier frequency bands.
Typical performance target: frequency accuracy of < 50 ppb.
Sync is the traditional technique used, with traceability to a PRS master clock carried over PDH/SDH networks, or using GPS.
Phase Lock with Latency Correction: Applicable to CDMA, CDMA-2000, UMTS-TDD, and WiMAX networks.
Limits coding time division overlap.
Typical performance target: frequency accuracy of < 20 - 50 ppb, phase difference of < 1-3 msecs.
GPS is the traditional technique used.
8.12.1 Wireless IP Synchronization Challenges
Wireless networks set to deploy over IP networks require a solution for carrying high precision timing to base stations. Two new approaches are being developed in an effort to meet this challenge:
Various Precision Timing Protocol (PTP) techniques
Synchronous Ethernet (SyncE)
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 77 of 167
8.12.2 Precision Timing-Protocol (PTP)
PTP synchronization refers to the distribution of frequency, phase, and absolute time information across an asynchronous packet switched network. PTP can use a variety of protocols to achieve timing distribution, including:
IEEE-1588
NTP
RTP
Precision Timing Protocol (PTP) Synchronization
8.12.3 Synchronous Ethernet (SyncE)
SyncE is standardized in ITU-T G.8261 and refers to a method whereby the clock is delivered on the physical layer.
The method is based on SDH/TDM timing, with similar performance, and does not change the basic Ethernet standards.
The SyncE technique supports synchronized Ethernet outputs as the timing source to an all-IP BTS/NodeB. This method offers the same synchronization quality provided over E1 interfaces to legacy BTS/NodeB.

8.12.6 Native Sync Distribution Mode
In this mode, targeting nodal configurations, synchronization is distributed natively end-to-end over the radio links in the network.
No TDM trails or E1 interfaces at the tail sites are required!
Synchronization is typically provided by one or more clock sources (SSU/GPS) at fiber hub sites.
Native Sync Distribution Mode
In native Sync Distribution mode, the following interfaces can be used as the sync references:
GE (SyncE)
Additionally, the following interfaces can be used for sync output:
GE/FE (SyncE)
Native Sync Distribution mode can be used in any link configuration and any network topology.
Ring topologies present special challenges for network synchronization. Any system that contains more than one clock source for synchronization, or in which topology loops may exist, requires an active mechanism to ensure that:
A single source is be used as the clock source throughout the network, preferably the source with the highest accuracy.
There are no reference loops. In other words, no element in the network will use an input frequency from an interface that ultimately derived that frequency from one of the outputs of that network element.
IP-10E’s Native Sync Distribution mechanism enables users to define a priority level for each possible clock source. Synchronization Status Messages (SSM) are sent regularly through each interface involved in frequency distribution, enabling the network to gather and maintain a synchronization status for each interface according to the system’s best knowledge about the frequency quality that can be conveyed by that interface.
Based on these parameters, the network assigns each interface a quality level and determines which interface to use as the current clock source. The
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 81 of 167
network does this by evaluating the clock quality of the available source interfaces and selecting, from those interfaces with the highest quality, the interface with the highest user-defined priority.
The synchronization is re-evaluated whenever one of the following occurs:
Any synchronization source is added, edited, or deleted by a user.
The clock quality status changes for any source interface.
The synchronization mode is changed for the node.
8.12.6.1 Native Sync Distribution Examples

9.2 RFU-C
RFU-C is a fully software configurable, state-of-the-art RFU that supports a broad range of interfaces and capacities from 10 Mbps up to 500 Mbps. This innovative and compact unit uses an “on-the-fly” upgrade method, whereby network operators only buy capacity as needed, savings on initial investments and ongoing OPEX. RFU-C operates in the frequency range of 6-42 GHz.
The RFU supports low to high capacities for traditional voice and Ethernet services, as well as PDH/SDH/SONET or hybrid Ethernet and TDM interfaces. Traffic capacity throughput and spectral efficiency are optimized with the desired channel bandwidth. For maximum user choice flexibility, channel bandwidths can be selected together with a range of modulations of from QPSK to 256 QAM. High spectral efficiency is ensured using the same bandwidth for double the capacity, via two carriers, with vertical and horizontal polarizations. This feature is implemented by a built-in XPIC mechanism.
With RFU-C, traffic capacity throughput and spectral efficiency are optimized with the desired channel bandwidth. For maximum user choice flexibility, channel bandwidths can be selected together with a range of modulations from QPSK to 256 QAM over 3.5-56 MHz channel bandwidth.
When RFU-C operates in co-channel dual polarization (CCDP) mode, using the cross polarization interference canceller (XPIC) algorithm, two carrier signals can be transmitted over a single channel, using vertical and horizontal polarization. This enables double capacity in the same spectrum bandwidth.

9.3.4 1500HP/RFU-HP Installation Types
FibeAir RFU-HP can be installed in a Split Mount configuration or in several All-Indoor options.
9.3.5 1500HP/RFU-HP Supported Configurations
These configurations are applicable for split mount or all indoor installation type:
Unprotected N+0 - 1+0 to 10+0 – Data is transmitted through N channels, without redundancy (protection)
Hot Standby - 1+1 HSB, 2+2 HSB – Two RFUs use the same RF channel connected via a coupler, whereby one channel transmits and the other acts as a backup (Standby). The 2+2 HSB configurations uses two RFUs which are chained using two frequencies and connected via a coupler to the other pair of RFUs.
N+1 Frequency Diversity - N+1 (1+1 to 9+1) – Data is transmitted through N channels and an additional (+1) frequency channel, which protects the N channels. If failure or signal degradation occurs in one of the N channels, the +1 channel carries the data of the affected N carrier. Additional configurations can be achieved using two racks, such as 14+2.
Note: Space Diversity can be used in each of the configurations.
When the 1500HP/RFU-HP is mounted in a Split Mount configuration, up to five RFUs can be chained on one pole mount (the total is ten RFUs for a dual pole antenna).
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 105 of 167
9.3.6 1500HP/RFU-HP All-Indoor Configurations
When the 1500HP/RFU-HP is installed in an All Indoor configuration, there are several installation options:
In ETSI rack – up to ten radio carriers per rack
In 19” open rack – up to five radio carriers per subrack
Compact assembly – up to two radio carriers in horizontal placement (without a subrack)
When using All-Indoor configurations, there are two types of branching implementations:
Using ICBs
Vertical assembly, up to 10 carriers per rack (five carriers per subrack)
Using OCBs
Compact horizontal assembly, up to 2 carriers per subrack
9.3.7 Branching Networks
For multiple carriers, up to five carriers can be cascaded and circulated together to the antenna port.
Branching networks are the units which perform this function and route the signals from the RFUs to the antenna. The branching network can contain multiple OCBs or ICBs. When using Split Mount or All-Indoor compact (horizontal) configuration, the OCB branching network can be used. When using an All-Indoor configuration (vertical), the ICB branching network is used.
The main differences in branching concept between the OCB and the ICB is the how the signals are circulated.
OCB – the Tx and the Rx path circulate together to the main OCB port. When chaining multiple OCBs, each Tx signal is chained to the OCB Rx signal and so on (uses S-bend section).
ICB – all the Tx signals are chained together to one Tx port ( at the ICC ) and all the Rx signals are chained together to one Rx port (at the ICC). The ICC circulates all the Tx and the Rx signals to one antenna port (see the components description below).

11. Management and System Security
The Ceragon management solution is built on several layers of management:
NEL – Network Element-level CLI
EMS – HTTP web-based EMS
NMS and SML – PolyView platform
Each IP-10 Network Element includes an HTTP web-based element manager (CeraWeb) that enables the operator to perform element configuration, RF, Ethernet, and PDH performance monitoring, remote diagnostics, alarm reports, and more.
In addition, Ceragon provides an SNMP V1/V2c/V3 north bound interface on the IP-10.
Ceragon’s management suite also includes a number of CeraBuild™ tools, which ease the operator’s task of installing, maintaining, and provisioning Ceragon equipment.
PolyView™ is Ceragon's Network Management System (NMS) that includes CeraMap™ , its friendly and powerful client graphical interface. PolyView can be used to update and monitor network topology status, provide statistical and inventory reports, define end-to-end Ethernet services, download software, and configure elements in the network. In addition, it can be integrated with Northbound NMS platforms, to provide enhanced network management. The application is written in Java code and enables management functions at both the element and network levels.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 129 of 167
Ceragon’s management suite also includes a web-based element management system (Web EMS), for advanced element management, and CeraBuild™ for specialized maintenance and provisioning.
Ceragon also offers NetMaster, a comprehensive NMS that provides centralized operation and maintenance capability for the complete range of network elements in an IP-10E system. NetMaster is built using state-of-the-art technology as a scalable, cross-platform NMS that supports distributed network architecture.
In addition, management, configuration, and maintenance tasks can be performed directly via the IP-10E Command Line Interface (CLI). The CLI can be used to perform configuration operations for stand-alone IP-10E units or units connected in a stacked configuration, as well as to configure several IP-10E units in a single batch command. In a nodal configuration, all commands are available both in the main and extension units unless otherwise stated.

11.1 PolyView End-To-End Network Management System
PolyView is a Network Management System (NMS) designed for managing large scale wireless backhaul networks.
Optimized for centralized operation and maintenance of a complete network, PolyView offers users a comprehensive set of management functions to simplify network management work.
PolyView’s client interface, CeraMap™, provides centralized, GUI based access to all network management functionality.
11.1.1 PolyView Main Features
The following are some of PolyView’s main features:
End-to-end traffic service management PolyView includes a service management GUI for provisioning, configuration, monitoring, and management of Ethernet services. Service view provides Wizard based provisioning, service topology maps, and GUI driven configuration of service paths and trails.
Fault management PolyView enables global management of network entity alarms with comprehensive alarm reporting. The alarms interface provides details of each alarm, including the alarm type and severity, raise and clear time, probable causes and corrective actions.
Additionally, all map entities, including network elements, links, trails, and services, are color coded, with the color indicating the status of the most current alarm.
Configuration management PolyView simplifies network elements configuration management, with centralized configuration file backup and rollback. PolyView’s broadcast configuration and software download utilities help the NMS user to manage groups of network elements.
Auto-discovery of network topology
PolyView’s auto-discovery feature enables it to accurately reflect the actual configuration of the network. This is particularly useful when installing PolyView, and in cases of network recovery.
IP-10E supports the Link Layer Discovery Protocol (LLDP), a vendor-neutral layer 2 protocol that can be used by a station attached to a specific LAN segment to advertise its identity and capabilities and to receive identify and capability information from physically adjacent layer 2 peers.
LLDP enables PolyView to discover the entire Ethernet LAN topology, because the IP address of at least one network element will be known and all network elements exchange LLDP information.
PolyView also discovers the configuration of each node based on the node’s IP address, discovered through auto-discovery of the network topology.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 131 of 167
Performance management Scheduled polling allows users to monitor network activity in real time and to keep historical performance monitoring information for future usage. For a more in-depth understanding of network performance, CeraWeb’s reporting interface is designed to help users identify activity patterns and anticipate problems before they occur.
Inventory and performance reports can be generated for the entire network, or for a selected subnet, group, trail, or service. Inventory reports provide information about Ceragon interfaces and links in the system. Performance reports provide information about radio, interface, and trail performance.
Network security PolyView is a secure system that enables administrators to control who uses the system, and which parts of the system can be accessed. Security is maintained by a combination of user access control features, audit logging, and secured interfaces.
Permissions are assigned to groups on a feature by feature basis. User access rights determine which parts of the network a user can view, and which operations users can perform for each subnet.
11.1.2 PolyView User Interface
PolyView’s network management GUI, CeraMap™, enables fast and easy design of multi-layered network element maps, and helps manage the network from the initial deployment stage through ongoing maintenance and configuration procedures.

11.4 System Security Features
To guarantee proper performance and availability of a network as well as the data integrity of the traffic, it is imperative to protect it from all potential threats, both internal (misuse by operators and administrators) and external (attacks originating outside the network).
System security is based on making attacks difficult (in the sense that the effort required to carry them out is not worth the possible gain) by putting technical and operational barriers in every layer along the way, from the access outside the network, through the authentication process, up to every data link in the network.
11.4.1 Ceragon’s Layered Security Concept
Each layer protects against one or more threats. However, it is the combination of them that provides adequate protection to the network. In most cases, no single layer protection provides a complete solution to threats.
The layered security concept is presented in the Security Solution Architecture Concept diagram. Each layer presents the security features and the threats addressed by it. Unless stated otherwise, requirements refer to both network elements and the NMS.

11.4.2 Defenses in management communication channels
Since network equipment can be managed from any location, it is necessary to protect the communication channels’ contents end to end.
These defenses are based existing and proven cryptographic techniques and libraries, thus providing standard secure means to manage the network, with minimal impact on usability.
They provide defense at any point (including public networks and radio aggregation networks) of communications.
While these features are implemented in Ceragon equipment, it is the responsibility of the operator to have the proper capabilities in any external devices used to manage the network.
In addition, inside Ceragon networking equipment it is possible to control physical channels used for management. This can greatly help deal with all sorts of DoS attacks.
There is a possibility of using secure channels instead or in addition to the existing management channels:
SNMPv3 for all SNMP-based protocols for both NEs and NMS
HTTPS for access to the NE’s web server
SSH-2 for all CLI access SFTP for all software and configuration download between NMS and NEs
All protocols run with secure settings using strong encryption techniques. Unencrypted modes are not allowed, and algorithms used must meet modern and client standards.
Users are allowed to disable all insecure channels.
In the network elements, the bandwidth of physical channels transporting management communications is limited to the appropriate magnitude, in particular, channels carrying management frames to the CPU.
Attack types addressed
Tempering with management flows
Management traffic analysis
Unauthorized software installation
Attacks on protocols (by providing secrecy and integrity to messages)
Traffic interfaces eavesdropping (by making it harder to change configuration)
DoS through flooding

11.4.3 Defenses in user and system authentication procedures
User identification
User and password data kept with the use of strong encryption techniques. This data is saved as binary file with hashing. It is unreadable.
Strong rules for passwords, such as length, string composition, history, and aging period, are defined and optionally enforced for all passwords.
User and session validity rules (such as inactivity timeouts and a threshold for the number of unsuccessful login attempts) are defined and enforced. Upon violation, sessions and users are suspended.
Remote authentication
Certificate-based strong standard encryption techniques are used for remote authentication. Users may choose to use this feature or not for all secure communication channels.
Since different operators may have different certificate-based authentication policies (for example, issuing its own certificates vs. using an external CA or allowing the NMS system to be a CA), NEs and NMS software provide the tools required for operators to enforce their policy and create certificates according to their established processes.
Server authentication capabilities are provided.
Authorization
In NEs users classifiable to groups, each group having separate and well-defined authorization to access resources. All security features configuration open only to the highest-permissions group.
In the NMS, it is possible to define arbitrary definitions of new permissions groups.
Centralized management
RADIUS protocol is supported in the NMS (RADIUS client).
RADIUS server is the responsibility of the operator.
The use of RADIUS is optional.
Attack types addressed
Impersonation
Unauthorized software installation
Traffic interfaces eavesdropping

Users with type of “administrator” or above can specify the web protocol.
11.4.5.2 SNMP
The SNMP agent supports SNMP v1, V2c or v3.
The default community string in NMS and the SNMP agent in the embedded SW are disabled. Users are allowed to set community strings for access to IDUs.
SNMPv3 connections are authenticated with a single user ID and password. Admin users can configure this user ID and password.
11.4.5.3 Server authentication (SSL / SLLv3)
All protocols making use of SSL (such as HTTPS) use SLLv3 and support X.509 certificates-based server authentication.
Users with type of “administrator” or above can perform the following server (IDU) authentication operations for certificates handling:
Generate server key pairs (private + public)
Export public key (as a file to a user-specified address)
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 141 of 167
Install third-party certificates
The Admin user is responsible for obtaining a valid certificate.
Load a server RSA key pair that was generated externally for use by protocols making use of SSL.
Non-SSL protocols using asymmetric encryption, such as SSH and SFTP, can make use of public-key based authentication.
Users can load trusted public keys for this purpose.
11.4.5.4 Encryption
Encryption algorithms include:
Symmetric key algorithms: 128-bit AES
Asymmetric key algorithms: 1024-bit RSA
11.4.5.5 SSH
The CLI interface supports SSH-2
Users of type of “administrator” or above can enable or disable SSH.
11.4.5.6 SFTP
SFTP can be used instead of standard FTP.
Users with type of “administrator or above can enforce secure FTP by disabling standard FTP.
11.4.6 Security log
The security log is an internal system file which records all changes performed to any security feature, as well as all security-related events.
Note: The Security log can only be accessed via the CLI.
The security log file has the following attributes:
The file is of a “cyclic” nature (fixed size, newest events overwrite oldest).
Readable only by users with "admin" or above privilege.
The log can be viewed using the following command:
/management/mng-services/log-srv/security-log/view-security-log
The contents of the log file are cryptographically protected and digitally signed.
In the event of an attempt to modify the file, an alarm will be raised.
Users may not overwrite, delete, or modify the file.

11.5 End to End Multi-Layer OAM
FibeAir IP-10E provides complete Operations Administration and Maintenance (OAM) functionality at multiple layers, including:
Alarms and events
Maintenance signals, such as LOS, AIS, and RDI.
Performance monitoring
Maintenance commands, such as loopbacks and APS commands.
OAM Functionality
11.5.1 Configurable RSL Threshold Alarms and Traps
Software Release i6.8 introduces the ability for users to configure alarm and trap generation in the event of RSL degradation beneath a user-defined threshold. An alarm and trap are generated if the RSL remains below the defined threshold for at least five seconds. The alarm is automatically cleared if the RSL subsequently remains above the threshold for at least five seconds.
The RSL threshold is based on the nominal RSL value minus the RSL degradation margin. The user defines both the nominal RSL value and the RSL degradation margin.
11.5.2 Connectivity Fault Management (CFM)
The IEEE 802.1ag standard defines Service Layer OAM (Connectivity Fault Management). The standard facilitates the discovery and verification of a path through 802.1 bridges and local area networks (LANs).
In addition, the standard:
Defines maintenance domains, their constituent maintenance points, and the managed objects required to create and administer them.
Defines the relationship between maintenance domains and the services offered by VLAN-aware bridges and provider bridges.
Describes the protocols and procedures used by maintenance points to maintain and diagnose connectivity faults within a maintenance domain.
FibeAir® IP-10 E-Series Product Description
Ceragon Proprietary and Confidential Page 144 of 167
Provides means for future expansion of the capabilities of maintenance points and their protocols.
IEEE 802.1ag Ethernet CFM (Connectivity Fault Management) protocols consist of three protocols that operate together to aid in debugging Ethernet networks: continuity check, link trace, and loopback.
FibeAir IP-10E utilizes these protocols to maintain smooth system operation and non-stop data flow.
